Die Kernaufgabe der Europ?ischen Zentralbank ist es, die Preisstabilit?t zu gew?hrleisten. Die Finanz- und Staatsschuldenkrise
hat der EZB die Rolle aufgezwungen, durch Notma?nahmen die Stabilit?t der W?hrungsunion zu sichern. Ihre Unabh?ngigkeit wird
zunehmend dadurch gef?hrdet, dass es in diesem Prozess zu einer Verquickung von Fiskal- und Geldpolitik kommt. W ünschenswert
w?re eine Rückkehr der EZB zu ihrer alten Rolle und eine Strategie, die für einen Abbau der weltweiten und europ?ischen Ungleichgewichte
sorgen k?nnte. 相似文献

Recent food price increases reportedly caused significant numbers of households to fall into poverty, particularly in the developing world. Most research into the welfare effects of these food price changes assumes constant demand or approximates second order substitution effects. Poverty forecasts with these assumptions may overestimate or underestimate the effect of food price increases in a nation where most households consume diverse food baskets. We account for full substitution by calculating a theoretically consistent food demand system, accounting for household responses to food price changes by decreasing some food purchases and increasing other food purchases. We use Mexican data to confirm the mitigation of adverse welfare effects from food price increases after accounting for country-specific dietary preferences in modeling demand. In comparison to previous literature, our welfare measures predict theoretically consistent numbers of Mexican households entering poverty due to recent food price changes. 相似文献

The generosity of public pensions may depress private savings and provide incentives to retire early. While there is plenty of evidence supporting the latter effect, there remains considerable controversy over whether public pensions crowd out private savings. This paper uses international micro‐data sets collected over recent years to investigate whether public pensions displace private savings. The identification strategy relies not only on cross‐country differences in generosity but also on differences in the progressivity or non‐linearity of pension formulas across countries. We estimate that an extra dollar of pension wealth depresses accumulated financial assets around the time of retirement by 22 cents. An extra 10,000 dollars in public pension wealth reduces the average retirement age by roughly one month, which implies an elasticity of years of retirement with respect to pension wealth of 0.15. 相似文献

This paper focuses on the ability of the labor market to efficiently match heterogeneous workers to jobs within a given industry and the role that globalization plays in that process. Using matched worker–firm data from Sweden, we find strong evidence that openness improves the matching between workers and firms in industries with greater comparative advantage. This suggests that there may be significant gains from globalization that have not been identified in the past — globalization may improve the efficiency of the matching process in the labor market. These results remain unchanged after adding controls for technical change at the industry level or measures of domestic anti-competitive regulations and product market competition. Our results are also robust to alternative measures of the degree of matching, openness, and the trade status of an industry. 相似文献

We apply well-known results of the econometric learning literature to the Mortensen and Pissarides real business cycle model. Agents can always learn the unique rational expectations equilibrium (REE), for all possible well-defined sets of parameter values, by using the minimum-state-variable solution to the model and decreasing gain learning. From this perspective the assumption of rational expectations in the model could be seen as reasonable. But using a parametrisation with UK data, simulations show that the speed of convergence to the REE is slow. This type of learning dampens the cyclical response of unemployment to small structural shocks. 相似文献
